The following materials descriptions are of a general PP is ductile at ambient temperature and has good impact strength. nature. Chemline should be consulted for material recommendations It also has good thermal stability up to 90°C (194°F) , higher than that on specific applications. of other thermoplastics such as PVC and HDPE. It is light weight. The THERMOPLASTICS specific gravity is 0.91 compared to 1.4 for PVC. It’s abrasion resistance is good, much better than that of PVC. This is a feature of Chemline Most plastics are made from synthetic resins (polymers) through PVC butterfly valves which have PP discs as standard. the process of polymerization. Two main types of plastics are Chemline PP pipe and fittings weld together very well using either butt thermoplastics and thermosets. Thermoplastic products are injection or socket fusion. The pressure losses in PP piping systems are lower moulded or extruded from compound material processed under heat than metal because of the smooth inside surfaces of the pipes. This and pressure. property also minimizes or eliminates deposits or bacterial growth. PP materials of construction PVC (Polyvinyl Chloride) is a poor conductor of heat, i.e. is a good insulator. Chilled or hot water The largest selection of Chemline valves and controls are moulded in systems in PP often require no insulation. PVC. This rigid gray colour material is unplasticized polyvinyl chloride. PP is very inert and relatively inexpensive, thus popular for high purity PVC is formed by the polymerization of the vinyl chloride monomer. water systems. The standard pigmented material is normally used. Unplasticized PVC or PVC-U has excellent mechanical and chemical Special grades include U-PP (unpigmented, natural) translucent material resistance properties at low cost. The working temperature range of sometimes preferred for pure water systems, pigmented black for the PVC valves is 0 to 60°C (30 to 140°F). Vinyl is plasticized PVC. The highest resistance to UV light, flame retardant grades to meet building added plasticizer produces a flexibile material for such products as code requirements, and electro-conductive grades for volatile media. tubing, but offers poor chemical resistance. Polypropylene is available in two grades: The PVC used for Chemline valves is identified by cell classification number 11564-A as per ASTM Standard D 1784. Suffix “A” refers to t)PNPQPMZNFS 11) NBEFGSPN5ZQF*SFTJODPOGPSNJOHUP"45. the highest chemical resistance rating. Most other PVC valves as well as D 4101, produced from 100% propylene monomer. PP-H is the most pipe and fittings have only a “B” chemical resistance rating. The special widely utilized. It offers a high strength to weight ratio and is stiffer PVC “A” compound used in Chemline valves resists attack of most and stronger than the copolymer grade. Piping is normally PP-H. a acids, strong alkalais, salts and many other chemicals. High chemical few Chemline valves are also PP-H. The working temperature range of resistance of this material allows its application on aggressive services PP-H back pressure valves for example is 10 to 70°C (50 to 158°F). such as 98% H2 SO4, dry chlorine and low pressure wet chlorine gas. t3BOEPN$PQPMZNFS 113 NBEFGSPN5ZQF**SFTJOQSPEVDFEGSPN PVC is attacked by chlorinated hydrocarbons, ketones, esters and some 94% propylene with 6% ethylene. PP-R is a bit softer but has better aromatic compounds. It can be used on solutions containing up to 1000 impact strength, is tougher and more durable than PP-H. Copolymer ppm solvents. polypropylene has better stress crack resistance and low temperature toughness than homopolymer at the expense of small reductions in Chemline PVC valves are non-toxic. They meet CSA standard B137.0 other properties. Most Chemline valves and all the pipe fittings are for toxicity and NSF/ANSI Standard 61 for contact with drinking water. PP-R. PP-R pipe is also available. The working temperature range of They are resistant to damaging effects of sunlight and weathering, thus Chemline’s PP-R ball valves is –20 to 80°C (–4 to 176°F) and up to painting is not necessary. 90°C (194°F) for diaphragm valves. CPVC (Chlorinated Polyvinyl Chloride) CPVC is PVC that has been chlorinated via a free radical chlorination reaction. It is similar to PVC in chemical resistance. Mechanically it is more ductile than PVC. It’s main difference is higher working temperature ratings and is therefore used where temperatures are too high for PVC or when an extra margin of safety is required. Valves are suitable for applications from 0 to 95°C (30 to 200°F). The CPVC compound used for Chemline valves is classified as 23567- A as per ASTM D 1784. The suffix “A” denotes conformance to the highest chemical resistance rating. Most other CPVC valves as well as pipe and fittings have only a “B” chemical resistance rating. The compound is non-toxic, conforming to CSA toxicity standard B137.0. PP (Pigmented Polypropylene) Polypropylene (PP) is a thermoplastic polyolefin made from the olefin propylene. A more modern term for polyolefin is polyalkene. Chemline offers piping systems, valves and controls normally in pigmented PP. The addition of grey-beige pigment prevents degradation due to ultraviolet light penetration. PP is used in a wide variety of applications from acids and alkali’s to organic solvents as well as pure water. PP is one of the best materials to use for systems exposed to varying pH levels, as many plastics do not handle both acids and bases well. It is excellent on acids such hydrochloric and phosphoric acid but unsuitable on strong acids www.chemline.com | AAV 05-14 | 3 Materials of Construction U-PP (Unpigmented Polypropylene) ECTFE has excellent chemical resistance (i.e. not subject to chemically U-PP is produced from high-purity virgin random copolymer. Chemline induced stress cracking) against halogens such as chlorine and bromine, offers PP pipe, fittings and valves in unpigmented PP. strong acids such as hydrofluoric and nitric acids, organic solvents and U-PP shows excellent purity levels when tested in standard static leach oils. ECTFE surpasses PVDF in resistance to strong bases and is the best tests (better than high-purity PVC) and has a superior surface quality, material for handling sodium hypochlorite even at high temperatures. i.e. smoothness (Ra=0.4 to 1.5 μm), making it a popular choice for ECTFE is not resistant to hot amines, sodium or potassium. high-purity water systems. It is suitable as piping for high purity water ECTFE offers excellent fire protection without addition of flame- systems, compliant with USP Class VI for pharmaceutical high purity retardant additives. It has a V-O rating according to the UL-94 vertical applications. It is also approved by the FDA for contact with food. The flame test. disadvantage of U-PP is it will degrade if exposed to UV light (sun light). PE (Polyetheylene) PVDF (Polyvinylidene Fluoride) Polyethylene is the polyolefin produced by polymerizing the olefin ® materials of construction PVDF also known as “Kynar ”, is a highly inert and pure thermoplastic ethylene. The ball in a Chemline Cavity Free ball valve is made of PE. fluoropolymer. It has many superior properties as a thermoplastic. They withstand abrasion better than PVC. PVDF has excellent chemical resistance against halogens such as chlorine and bromine, strong acids such as hydrofluoric and nitric acids, PSU (Polysulfone) organic solvents and oils. PVDF is not resistant to hot bases. Polysulfone is a thermoplastic polymer containing a sulfonyl functional group (-SO2-) attached to two carbon atoms. It is offered as a tube PVDF has much higher abrasion resistance than other thermoplastics. material for Chemline variable area flow meters. It offers high impact Chemline’s butterfly valves with optional PVDF discs offer extended life strength, high dimensional stability and good optical transparency, all on abrasive applications. important for accuracy and easy reading of the flow meters. Working PVDF (Polyvinylidene Fluoride) temperature range of the PSU flow meters is 0 to 90°C (32 to 194°F) It has remarkable strength over the largest working temperature range. depending on end and nut materials. While the standard PVC tube flow The working temperature range of PVDF ball valves is –40 to 100°C meters are not recommended for gases, PSU ones are. It is also more (–40 to 212°F) and up to 120°C (250°F) for diaphragm valves with a suitable for high purity water applications. The chemical resistance is PVDF bonnet. PVDF’s impact strength is over twice that of PVC. The good generally, but lower than that of PVC. valves and piping will withstand mechanical abuse at sub-freezing PA (Polyamide) temperatures.
